This is the latest expansion for the game Among the Stars. It introduces a couple of new game mechanics, such as spaceships that dock at your station and take up spots so that it alters your choices about adding new cards to the layout. It can also function as a stand-alone game. The reason that I haven't pledged yet is that I have already spent a ton on previous Among the Stars projects to get a lot of game material, but I've only ever played the game once. It's hard for me to justify the expense at this point, as much as I would like to have all the cards. I suspect I will cave eventually, but I'm holding out for the moment.
